Ti has to make sense internally before it's accepted externally. Things aren't taken at face value until they match an internal logic scheme. Te is the opposite - internal thoughts aren't accepted unless they match an external logic scheme, like a procedure.
And Ti users use Ne or Se with it, meaning that they gather information without judging it and want to get as much information before making the decision.
Te users use Si and Ni, and because they judge information from external world they dismiss illogical info(or what seems to be illogical or irrelevant(and this is what makes them weaker imo )) and only take logical facts inside, so that they can gather the facts from inside with Si or Ni easily.
Ti forms opinions, but does not promote actions to any great degree. It is a preferance for shifting through information, looking for logical conclusions or irregularities. Any found may be noted with interest, and the extroverted percieving function then goes looking for more.In ITPs, percieving serves judging, so the person tends have a more narrow focus on what appeals to Ti. In an ETP, perceiving rules, and they tend to cast the net wider drawing in a wide range of disperate information which Ti then goes through, possibly finding links between unexpected things.
Te is a method of relating to and dealing with the outside world. It utilises the inormation fed to it to assertain what needs to be and how best to go about it. It's conclusion provide a spur to action. In the primary possition, more time is spent on deciding how to do rather than what to do. When introverted percieving is stronger, more thought is given to the "what" part.
Te is used heavily in empiricism, particularly in the scientific method. It's about hypothetical/deductive reasoning. This is NiTe in action. A practical application of Te would be if your flashlight was not working, and you had to decide what the problem was: light bulb is dead, or batteries are dead. You experiment to see if the flashlight's batteries really are dead, likewise with the light bulb. Once you have figured out what the problem is (the infamous Ni "ah-ha!" moment), you implement the action necessary to correct the problem: i.e. change the light bulb, or change the battery. You have made sense of the outside world via deductive reasoning, and have solved a problem, which is asking "how do I get the flashlight to work?".
Ti on the other hand is more of an internal logical system, a formation of your own mental model/representation of the world. TiNe is illustrated often in systems thinking and systems dynamics, where you construct a relationship between variables and represent how you internally interpret things. It is about internal organization of your thoughts.

Ti- looking at the details to make sure they are consistent
I disagree with that. There's so much more to it than that. I'm all about the big picture. Most N's are. S's thrive on details. I just happen to be able to notice/pick apart logical inconsistencies within that big picture.
As an example, when I've had people working for me in the past, I didn't really care much how they got their job done - as long as they got it done well and in a timely fashion. I didn't care to be bothered with the details - be autonomous, be creative, and figure it out. I'm here if you really do need me (like any boss would be), but I want you to figure out the details 80-90% of the time - that way I can focus on the big picture (and my own details - which we all have plenty of each day).
Where my proficiency with details comes into play is when people say they are doing one thing, but are actually doing something else. Or if the organization as a whole (and its VIP's) say that it is going in one direction, but is really going in another direction. "Our mission is to serve our target market with excellence." Great, but you're not doing that. You're serving some of your market and some of someone else's market - and you're not doing it with excellence, you're doing it with mediocrity. So, you're missing your mission on two counts. We see all of these kinds of things, but it's only because we're constantly scanning the big picture. Because I'm constantly scanning the "big picture" (and filing away what I observe into the Si database), if I see something that is inconsistent later that day or next month (or even next year), it's not going to go unnoticed. But, here's the key: if it's not something that affects the overall outcome or the big picture, I don't really care. I don't have the desire nor the time to focus on nonsense. Not all details are nonsense, but some of them are.
